Ph.D. Yale University (Forest Ecology), 1990.
I am interested in determinants of species distributions and abundances at the community and landscape scale, related species interactions such as colonization, competition, predation, and symbiosis, the evolution of life history characteristics, and how these phenomena are related to resource supply rates and nutrient fluxes.
My interest span across multiple aspects of forest ecosystems and factors that influence plant productivity.
Graduate Research Topic
I am currently studying the health and productivity of sugar maples based on available soil nutrients in the White Mountains of New Hampshire. My research project is striving to determine what nutrients influence the sugar concentration of maple sap and whether maple sap sweetness can be increased by application of calcium, nitrogen, or phosphorus fertilizer in a forest stand.

I'm interested in forest-based environmental issues that raised currently. I'm more focused on nutrient cycling in forests and the way to assess the forest health.
Graduate Research Topic
My project is detecting the change in tree tissue chemistry over time in Northern Hardwoods. Research,conducted in Huntington Wildlife Forest,will show a change in concentrations of tree nutrients in different tree components over time and detail the uncertainties of processing long-time detecting studies in tree nutrients..
